如何以编程方式将控件添加到窗体？

Question

我正在尝试在面板内添加一个控件(Label).请看代码:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace AddControlProgramatically
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Label lbl = new Label();

            for (int x = 0; x <= 3; x++)
            {
                //create new label location after each loop
                //by multiplying the new value of variable x by 5, so the new label 
                //control will not overlap each other.
                lbl.Location = new System.Drawing.Point(52 + (x * 5), 58 + (x * 5));
                //create new id and text of the label
                lbl.Name = "label_" + x.ToString();
                lbl.Text = "Label " + x.ToString();

                this.panel1.Controls.Add(lbl);
            }
        }
    }
}

这是表格.我想要完成的是以编程方式生成3个不同的控制标签.但正如您所看到的,它只显示最后一个.请帮我解决这个问题.我知道我的代码有问题(导致它不能正常工作).谢谢......

Answer 1

放入Label lbl = new Label();循环内部.

并使偏移更大,改变这个......

 lbl.Location = new System.Drawing.Point(52 + (x * 5), 58 + (x * 5))

...至:

lbl.Location = new System.Drawing.Point(52 + (x * 30), 58 + (x * 30))
